Nucleotides that form the strands of the DNA structure are complex molecules which consist of both a phosphate moiety and a nucleobase (adenine, guanine, cytosine or thymine) joined to a five-carbon sugar (deoxyribose).
The DNA structure consists of two chainlike molecules (polynucleotides) that twist around each other to form the classic double-helix. The cell s machinery forms polynucleotide chains by linking together four nucleotides.
